PAPER-MAKING- APPARATUS.

Toall'whom it ma concern:

die it known hat I, James I). XVAGG, a citizen of the United States, resid ng at Appleton, in he county of Outagamie and State of Wisconsin, have invented new an useful Improvements in Paper-Making lipparatus, of which the following 1s a specification The present invention has reference to remaking, apparatus, and more espeto apparatus for reeling or winding the web of paper after the same has been size bath and before final drying. proposes certain hereinafter-described improsements whereby Wrinkhngbhstermg and, above all, breaking of the webv at the I ,d through the poigt where the actual winding takes place,

Anembodimentpf the invention 15 illusthe accompanying drawing, whereof;

Figure l is a side illustration of the 11mproved wihding-,.me hanism; Fig. 21s a Plan view of Fig. 1; Fig. 3 is an enlarged, fragmentalview of one of the rolls; and Fig. 4 is a side-elevation of a modification. In said drawing, 1 indicates, enerally,

the strip or web of paper undergoing treatnept, the bath of size through which the same is passed, after having prev ously been engine-sized and dried, as susual. On leaving the size bath, the web is passed betwe n'the rolls 3 and 4, which s r e both to and to remove the excess size... and fro hese ro ls it is led, while still set, to the winding mechanism. The latter preferably consists of a rotating drum or other suitable dri e i, an a r l from the drum and on which it is wound up by $95011 of its frictional engagement with the same. In the construction shown, the e ds of th drum h f fit in U-shap bearin 9 whose stems are fastened to the tops o th Standards 10 which constitute the d um support. r

the feed rolls 3 and 4 and the winding mechanism are interposed instrumentalities which embody the most important features of the invention and which are employed both to tension and take up slack the still wet web, and to hold the latter anysustained dragging or drawing action Specification of Letters Intent.

thereon. In the construction represented in Figs. 1 and 2, separate rolls 11 and 12 are utilized for the purposes stated, and, between these rolls, a third roll 13. The roll 11, in this instance, constitutes the take-up and tension. means, and is supported a slight distance above and in front of roll & in a pair of bearing blocks l l formed with upwardly'opening sockets 15 for the reception of the roll ends. These blocks are slidably mounted upon a pair of vertical pins 16, and are yieldingly tion by expansible coil-springs 1.8, the said pins being connected in any desired manner to the trough or tub containing the size. The rolls 12 and 13 are carried by pairs of vertical supporting rods 19 and 20, suitably connected together and braced, the lower ends of the rods 19 beingbentaround and fastened to the bearings 9, while the corresponding ends of therods 20 are fastened to the standards 10. The tops of these rolls are disposed above the top of drum 5 and slightly below that of roll 11, their relative arrangement being such that the top of roll 12 is a little lower than that of roll 13, so that the web has a very gradual downward inclination between the rolls 11 and 12.

The roll-l2 actsgas the means for guiding the web to the winding mechanism, and it is so positioned that the web passes from it in held in elevated posia perfectly straight line direct to the" nip intersection between the aforesaid plane and such surfaces, as will be understood. As tle strain upon the web during drum windin is ordinarily greatest at the point where it passes around the drum, and varies according to the extent of contact between the web and the-drum surface, (21. 6., thcs urface area of contact), and, above all, since wet paper, being weaker, requires very much more careful handlingfithan dry, it is apparent that by decreasing the area of surface contact between the web and drum to a minimum, the dragging action is reduced to a point where it is practically negligible, with proportionate avoidance of breakage. For the same reasons, wrinkling and blistering of the web, with resultant waste thereof, are

avoided, owingto the employment of roll 1'.

and its arrangement as above indicated since the minimum contactarea completelyprevents the entrance and. accumulation of air behind the web and between'the same and the drum. It is preferable to construct face, directly to the winding mechanism, the

latter being disposed comparatively close to the sizing bath and, if desired, below the floor level.

To enable reel 8 to. be accurately positioned for the above purpose, aswell as to permit the degree of pressure exerted by it upon the drum to be varied, in order to conform to. existing conditions, any suitable device, such,'for instance, that shown, may be employed. In this form, the said device embodies a pair of upwardly-inclined arms 21, which constitute the reel support and which are pivoted at their lower ends to the standards 10, the upper ends of thesearms being connected by adjustable links 22 to the corresponding ends of a pair of similarly inclined arms 23 fixed to a horizontal shaft 24:. The latter is actuated from a vertical, controller shaft 25 through the agency of worm gearing 26, the shaft 25 being equipped with a-ha-ndwheel or other operating element 27. Rotation of the controller shaft thus effects a corresponding movement of shaft 24 and, in consequence, a rocking movement, of arms 23, with the result that the inclination of the reel-car rying arms 21 is varied. After the reelhas been filled, it is removed from its support, with the Web in a wet state thereon, and subjected to any further treatment desired.

Having fully described my invention, I claim 1. In an apparatus for winding wet paper web, the combination with means for sizing the web and size-expressing means operative to feed the wet web from the sizing means,

7 of a revoluble cylindrical drum, a reel resting against the drum and operative to receive and wind the wet web into a roll,

and web-guiding means interposed between the size-expressing means and said drum A and reel and operative to direct the wet web to the line of nip between said drum and reel.

' 2. In an apparatus for winding wet paper web, the combination of means for wetting the web, and means for'feeding the wet j web forward therefrom, "of-'a-revoluble cylindrical winding drum, a reel resting against the drum for windingthe' wet web into a 'roll, and means interposedbetwe'en s'aiid feeding means and said drum and reel and guiding the wet web directly to the line of nip between said drum and reel.

3. In an apparatus for winding wet paper web, the combination with means for Wetting the web, and means'for feeding the wet web forward therefrom; of a revoluble cylindricalwinding drum, a; reel resting against the drum for winding the wet web into a 'roll, and Web-guiding means interposed between-the web-feeding. means and said drum and reel and operative to ting the web, and means for feeding thewet web forward therefrom, of a,'revoluble c3 lindrical winding drum, a 'reel/resting' against thedrum for winding the wet we into a roll, said drum. and'reel' being located below the level of said feeding means, and guiding means embodying a yieldably-acting roll cooperative with the web at avpoint between said feeding means -and the drum and reel and directing the web to the line of nip between said drumand reel and to maintain a yielding tensioni on the web.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit nesses.
